Hope it helps........ ✨

Explanation:

• When the light ray is incident normally on the plane mirror then by using laws of reflection angle of incidence is equal to angle of reflection. Hence, as the angle of incidence is zero degree angle of reflection is zero degree.
• reflected ray will reflect back in same path as that of incident ray.
